Eyewitness: Johnny McDaid supports Courteney Cox

Courteney Cox and Johnny McDaid were ''very touchy-feely'' at a screening of her directorial debut, 'Just Before I Go,' on Thursday night.

The former 'Friends' star walked the red carpet with the Snow Patrol rocker, 37, at the Tribeca Film Festival in New York City, amid rumors they are engaged, and stayed by each other's side all night.

A source told E! News: ''Courtney and Johnny were very sweet together and very touchy-feely. He constantly had his hand on her hip or she would put hers on his chest when they spoke. They seem really happy.''

But the 49-year-old actress brushed off speculation about the diamond ring on her engagement finger, saying: ''This is not... the question at hand. That I've worn forever.''

The brunette beauty, who started dating the pianist in September, was later spotted supporting her boyfriend in front of the stage, as he performed with his bandmates at the movie's afterparty at The Flatiron Room.

An eyewitness said: ''She was a very proud girlfriend.''

A source claimed earlier this week that the duo have been talking about adopting a baby together, as Johnny has formed a close bonded with the actress' nine-year-old daughter Coco, her child from her previous marriage to David Arquette.
